Abstract

A document rights management system (DRM) defines an unrenderable origin designator in a media item that does not display or alter the physically rendered version of an instantiation of the media item. The unrenderable designator does not appear as an obscured or occluded feature in a printed or displayed versions. The rendered version is unaffected by the unrenderable designator because it does not result in any displayable features. The unrenderable designator is stored in a display list of the media item and appears as an attribute of objects such that the function to cause the display object to be undisplayable, or unrenderable, are not immediately apparent. The DRM system encodes a designator in an attribute of a display object for rendering according to a media rendering format such as PDF, such that the designator causes the display object to be unrenderable and indicates the origin of the media item.
